Influência da superabundância por Aulonemia aristulata (Bambuseae) sobre o banco de sementes transitório em um fragmento de Floresta Atlântica

Abstract: Este estudo avaliou a estrutura e composição de espécies no banco de sementes transitório em duas áreas de mata atlântica do Parque Estadual Fontes do Ipiranga: uma área onde o bambu nativo Aulonemia aristulata é superabundante e outra área sem bambus, ambas localizadas em um fragmento de floresta secundária do Domínio da Mata Atlântica. Nossa hipótese foi a de que o banco de sementes transitório da área onde o bambu é superabundante possui menor número de sementes e diminuição da riqueza de espécies comparada… Show more

“…The low number of seeds sampled in Area 3 may be related to the commercial eucalyptus planting. Monodominant areas such as eucalyptus stands or bamboo species massifs are reported as limiting barriers for fauna and seed rain dispersal (Marsden et al, 2001;Bona et al, 2020), the seed bank (Vinha et al, 2017) and natural regeneration (Felker et al, 2018). In addition, the eucalyptus matrix can hinder the circulation of native seeds of anemochorous dispersion, as it also acts as a barrier to wind circulation (Piña-Rodrigues & Aoki, 2014).…”

“…Another impact is the presence of some species like Pteridium sp. or bamboos, that can dominate the initial or secondary forest, having an impact on seed bank density and richness (Vinha et al, 2017, Lima et al 2012. Lastly, environmental effects such as elevation (slope) also affect soil seed banks, with lower abundance and richness in steeper slopes.…”
